Rock core sampling drilling machine capable of avoiding friction overheating

Abstract

The invention relates to the technical field of rock core sampling, and particularly discloses a rock core sampling drilling machine capable of avoiding friction overheating, the rock core sampling drilling machine comprises a base and a motor, the top of the base is fixedly provided with a pneumatic assembly; the motor is arranged on the base, a drill rod can be driven by the motor to rotate, the drilling effect on soil is achieved, a piston rod and a piston block in a pneumatic assembly slide up and down and can be matched with an air outlet pipe to inject air into a water storage barrel, water in the water storage barrel can be conveniently injected into a sleeve, and the water storage barrel is convenient to use. According to the device, soil can be wetted conveniently, drilling of the drill rod is facilitated, the piston rod is combined with vertical movement of the motor and the drill rod, redundant labor cost can be reduced, meanwhile, the device is easier and more convenient to operate, meanwhile, the pressure resistance of the inner wall of the drill rod can be enhanced through mutual cooperation of a first reinforcing rib and a second reinforcing rib, and the service life of the device is prolonged. Therefore, the service life of the drill rod is prolonged.

Description

technical field [0001] The invention relates to the technical field of rock core sampling, in particular to a rock core sampling drilling rig which avoids frictional overheating. Background technique [0002] With the rapid development of science and technology, people can use new equipment to explore the conditions of the soil and rocks under the ground, and use the samples sampled by exploration to cooperate with the detection device to detect the mineral content under the soil, so as to facilitate the later analysis of the soil under the soil. The minerals are mined, and the existing commonly used rock core sample sampling device generally uses a drilling rig to drill holes in the surface layer of the soil, and then utilizes a drill pipe to sample the rock core. [0003] However, when the existing core sampling drilling rigs that avoid frictional overheating are actually used, they need to cooperate with water spraying devices to facilitate drilling. The effect is to mak...

Problems solved by technology

[0003] However, when the existing core sampling drilling rigs that avoid frictional overheating are actually used, they need to cooperate with water spraying devices to facilitate drilling. function, so that the water inside the sprinkler device can continuously enter the inside of the drilling machine, and this increases the construction manpower, increases labor costs, and wastes labor productivity

[0004] And in order to meet the normal flow of water flow, the drill pipe must be hollow, and the hollow drill pipe will have the problem of reduced anti-extrusion ability, and at the same time, when the drilling machine is used for a long time, the drill pipe will appear friction The phenomenon of overheating will affect the service life of the drill pipe
